Disaster recovery/tolerant solutions for Linux workloads

Disaster recovery or protection technologies have evolved and provides highly matured solutions to safeguard the IT assets of an organization in an event of a disaster. Despite achieving the sophistication in the development of disaster recovery or protection technology, some of the incidents mentioned below are common which gets the attention of public as news provider agencies make them available as breaking news clips.

  • Banking operations stopped for a week
  • Retailers unable to service customer requests due to failure of computer systems recovery
  • Shutdown of stock exchange trading operations and so on

Additionally, government regulations also mandate the business organizations to build, verify and disclose the preparedness of disaster protection of their critical IT assets of which data resides at its core.

 

One of the common reasons for failures is that complexity in integration of various products/technologies involved in providing disaster recovery facility and verification of the systems response to an event such as failure, fault or disaster in a real production deployment scenario of a customer. HP as a large technology company with interests spanning across Servers, Storage, Networking and Highly available/Disaster tolerant Serviceguard clustering solutions, they come with a unique quality which is time tested and proven in the real world failure scenarios.  With decades of experience serving the mission critical customers, HP understands the customers best in the disaster recovery field. As a result we have built the products and also tested them in our lab environment covering various real deployment scenarios to identify and fix any issues before these products get deployed in a customer environment. This effort minimizes or eliminates the risk of product failures when they are expected to serve at a critical situation.
